Problems with relative dating

Brongniart was the first to use fossils to date rock strata., which states that geologic events are caused by natural processes, many of which are operating in our own time.

This matching process is called correlation, which has been an important process in constructing geological timescales.

Some fossils, called index fossils, are particularly useful in correlating rocks.

Theconcept of geologic time or deep time was a logical consequence of this theory.

In 1788 John Playfair came to see Hutton’s Unconformity in Inchbonny.

Correlation can involve matching an undated rock with a dated one at another location.

Suppose you find a fossil at one place that cannot be dated using absolute methods.

This law was independently discovered by William Smith (1769-1839), a British engineer, while working on excavations for canals in England (Winchester, 2002 p.
